Address Switches S1 and S2
S1 an S2 are hexadecimal switches that are used to set the I/O Controller’s address. If the system
contains more than one I/O Controller, each device must be set with a different address. The device’s
addressing should be set in sequential order starting with address 01. Switch S2 sets the first digit and
switch S1 sets the second digit.
Example:
Address 01:
S2 = 0, S1 = 1
Address 02: S2 = 0, S1 = 2
Address 03: S2 = 0, S1 = 3
N
OTE : After changing the board address, the RESET button must be momentarily depressed for the new
address to take effect.
DIP Switch S4
An 8-position DIP switch S4 sets various data parameters and operation parameters of the I/O controller.
The following tables indicate each switch position and the corresponding settings/functions.
DIP switch S4 positions 1-3 set the serial data line baud rate as follows:
